vue-docgen-api: failed to parsed when exported component use "as" with typescript

Current behavior We have exported components this way (for better typing extended components with composition api)

import { defineComponent } from '@vue/composition-api'
import CeHeader from './CeHeader'

const CeHeaderTheme = defineComponent({
  extends: CeHeader
})

export default CeHeaderTheme as typeof CeHeader

But this way of exporting causes warnings in storybook:

[vue-docgen-loader] failed to parse the component file with docgen-api: No suitable component definition found on...

To reproduce

Just export some component as default and add some as typeof operator:

export default {
  name: 'Test'
} as {
  name: string
}

Expected behavior

I would like to use “as” operator without any warnings.

@elevatebart I saw your changes in your repository, I have tested it with my current code base and it works great. I have crated PR to storybook to bump your package in this repository. Thank you for your time ❤️
